WAGON-JAG K.

SPECIFICATION forming part of Letters Patent No. 400,109, dated March26, 1889.

Application filed July '7, 1887- Serial No. 243,689. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM R. MOORE, of Unionville, in the county ofChester and State of Pennsylvania, have invented a new and usefulImprovement i n Wagon-Jacks, of which the following is a specification.

My invention relates to an improvement in lifting-jacks; and it consistsin the peculiar construction and combination of devices that will bemore fully set fort-h hereinafter, and particularly pointed out in theclaim.

The object of my invention is to provide a very light, cheap, and simpledevice, wherein the said link will act in a novel and effective mannerto support the lever and permit the same to be adjusted easily andquickly, and also to permit the lever to be removed from or adjustedupon the standard, if desired.

In the accompanying drawings, Figure 1 is a perspective of a jackshowing the lever pivoted securely to the upper end of the standard.Fig. 2 is a side elevation of a modification of my jack, showing meansfor adjusting the lever vertically.

My device, as shown in Fig. 1, consists of a double standard formed oftwo uprights, A A, bolted at their lower ends to the outer sides of abase, B. A hand-lever, O, is held between the upper ends of thestandards A A by a pivot-bolt, D, which also holds the upper ends of thestandards securely together. A loop, E, of flexible wire or sheet metal,has an enlarged end, 6, to completely embrace the standards A A, and isdrawn together at its opposite end and connected by a staple or eye, a,at or near the handle end of the lever O. The loop E is made of a singlepiece of metal linked together at 6 and is cheap, simple, and effectivein operation in connection with the smooth unnotched sides and edges ofthe standard. The loop is connected to the under side of thelever-handle, and may be lifted by the fingers when the lever isadjusted. When the fingers release the loop, the free end thereof willdrop down upon the standard and will surround and closely embrace thesame when the hand is removed from the handle of the lever and theweight of the load comes upon the heel end thereof, thus holding itsecurely in any adjusted position.

The jack may be easily carried about from place to place, and may behandled and manipulated entirely with one hand. It is made entirely ofwood, excepting the pins and metal wire loop.

In the modification shown in Fig. 2 the upper ends of the uprights A Aare securely bolted to a piece, a, and the upper ends of the standardsare made with. a notch or a series of notches, a, into which thepivot-pin may be placed for adjusting said pivot upon the standards tosuit axles of different heights and for completely removing the leverfrom the standard when desired. This can be readily accomplished, as theloop E embraces the entire body of the standard, and the stand- 7 ardmay be shifted entirely through the loop.

I am aware that jacks have been constructed with a standard, a leverpivoted to the upper end thereof, and a link connecting the handle end,of the lever with the standard, and do not broadly claim such device.

I claim as my invention and desire to secure by Letters Patent In awagon-jack of the character described, a standard having alifting-lever, the longer arm of which has an eye or staple secured atthe end thereof, through which a metal loop passes, one end of said loopbeing prolonged to form a stirrup and terminating in a hook whichengages a similar hook on the shorter end of the loop for binding thestirrup against the standard, substantially as described.
